The Twitter barrage comes as both the Associated Press and Washington Post report that Trump is considering firing Sessions, who was the first sitting U.S. senator to endorse the celebrity real estate mogul during the campaign.

But Trump is upset that Sessions recused himself from all campaign-related investigations, including the probe into whether any Trump associates colluded with Russia during the campaign. Sessions recused himself in March after it was revealed he had undisclosed meetings with the Russian ambassador.

And though the campaign ended more than eight months ago, Trump has repeatedly tried to turn the Russia spotlight back to Clinton.

During the campaign, Trump constantly attacked Clinton as “crooked” and hinted if elected he might direct his attorney general to investigate her.

But after his election, Trump appeared to back away from the idea, saying, “I don’t want to hurt the Clintons. I really don’t. … I think we have to get the focus of the country into looking forward.”

That appears to have changed. On Tuesday morning, Trump also questioned why Sessions is not probing what Politico reported in January were Ukrainian government attempts to help Clinton’s campaign undermine him during the 2016 presidential election. He tagged Fox News host Sean Hannity, a loyal Trump ally, in the tweet.

Ukrainian efforts to sabotage Trump campaign – "quietly working to boost Clinton." So where is the investigation A.G. @seanhannity

If Trump were to fire Sessions, the political fallout could be even greater than his sudden termination of FBI Director James Comey. Sessions is a fellow immigration hardliner who is well-liked by Trump’s base and supported by former GOP senators.

And Deputy Attorney General Rod Rosenstein, who has also drawn Trump’s public ire, would become acting attorney general. Rosenstein appointed special counsel Robert Mueller to lead the Russia investigation after Trump fired Comey.

“I have an enormous amount of respect for the attorney general,” Scaramucci replied. “But I do know the president pretty well, and if there’s this level of tension in the relationship that’s public, you’re probably right.”
